UNITED STATE LEWIS a. storms, or nrsnrow, Kansas RAILWAY SIGNALING APPARATUS.

To all whom-it may camera:

Be it known that 1. Lewis A, YOUNG, a citizen of the United States, residing at Bigelow, in the county of Marshall and State of Kansas have invented certain new and useful Improvements in Railway Signaling Apparatus; of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to railway signal.- ing apparatus, and more particularly to a control for crossing and similar signals. 7

An importantobject of the invention is to provide a device of this character which is mechanically operated and which is dependable in its operation.

A still further object of the invention is to provide afdevice of this character which is latched in its various positions so that accidental operation thereof is prevented These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, and wherein Figure 1 is a plan view showing a section of railroad track being provided with signal mechanism constructed in accordance with my invention; a

Figure 2 is a side elevation, partially in section, showing the operating members and signals; V

Figure 3 is an enlarged vertical sectional view taken transversely of the trip;

Figure 4 is a vertical sectional view taken through the trip;

Figure 5is a transverse sectional view through the signal element;

Figure'G is a view showing the positions of the trip members when the block is cleared.

Referring now more particularly to the drawings, the numeral 10 indicates a stand for a crossing signal including a base 11, a member 12 rotatable upon the base and having a partially toothed periphery, and a standard 13 extending upwardly from the base and'provided in its upper end with a signaling element 14 of any suitable character. The base has means 15 for maintaining in engagement with the toothed periphery of the rotatable member 12 a raclr bar 16, so that by longitudinal movement of the rack bar the member 12, and accordingly the signal 14:, is rotated. Such a signal is arranged at a crossing or otherpoint where 1924. Serial No. 744,955.

and the other of the bars is similarly shifted. P

The construction of the train-operated member 17 is more particularly illustrated in Figures 3 and 4, in which figures the numeral 21 designates an angle plate, one flange of which is secured to the tie 22 and the other flange of which extends upwardly into proximity to the rail. Thepart-ially toothed pes riphery serves as alimit to the amount of rotary movement which may be imparted to the signal and accordingly as a limit to the amount of movement which may beirnparted to the rigid rods 18. The last named flange. indicated at 23.parallels the rail and has pivotally secured thereto as at 24 a lever 25. to the lower end of which the associated rod 18 is pivotally connected. Due to the fact that movement of the rod is limited. swinging movement of this lever will also be limited. i

The opposite end of the lever is forked, the fork forming diverging arms 26. one of which is vertically directed at each limit of movement of the rod 18. Pivotally' secured v to the opposite side faces of the lever, as

.at 27 and associated with each arm is a telescopic arm extension 28 including side walls 29 slidably embracing the sides of the arm, an outer wall 30; and an end wall 31. Between the outer wall 30 adjacent the pivot point 27 and thearm, a spring 32 extends normally maintaining these extensions in the position shown in full lines in Figure 4, at which time the end walls 31 thereof engage against the adjacent faces of the arms 26. I

i It willfibe readily seen by an inspection of the drawings that these extensions are rigid to the arms when force is applied thereto so that it engages the end walls 31 thereof, but that when this force is applied to the outer walls 30 thereof these extensions may telescope upon the arms and move out of thepath of the article applying force thereto. In attaching the lever 25 to the angle plate, care is taken that the upper ends of the arms when in vertical or operz tive position are below the plane of the train-carried member 33 which coacts with the trips. IVhen the block is empty, the device is positioned as shown in Figure (5 and each has an arm 26 vertically directed and having its operating face 26 facing toward the outer end of the block. If a train now enters the block, the train-carried member 33 will engage solidly against the face 81 of the telescopic extensions, and since this telescopic extension is rigid to the arm, any such engagement will more the arm, and accordingly the lever, during its passages thereover. This will cause not only the engaged train-operated member but also the train-operated member at the opposite end of the block to assume positions as shown in Figure 2, at which time each trip will have a vertically extended arm disposed with its operating face toward the center of the block. 7

It will thus be seen that it does not matter whether the train after once entering the block leaves the block by the same end at which it entered or by the opposite end, the same operation ofthe trips will result. If while the block is occupied, a second train enters the block the engagement of the train-operated member 33 thereof will be with the face 30 and the telescopic exten sion 28 will be moved downwardly upon the arm, permitting passage of this traincarried member without any further operation of the trip or without placing undue strain thereon.

Certain changes and modifications of the structure hereinbefore set forth being possible without in any manner departing from the spirit of my invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim y 1. In combination, a si nal capable of limited rotation and a trip for operating the signal rigidly connected therewith whereby said signal limits the operation of the trip, said trip being mounted for oscillation and embodying a pair of arms adapted to be alternately disposed in the path of atraincarried member. each of said arms being formed in two sections. one of which is adapted for engagement by the train-carried member. said section being yieldably mounted to permit passage of the traincarried member upon engagement of the train-carried member therewith in one direction without operation of the trip and being rigid to its associated arm upon engagement of the train-carried member there with in the opposite direction whereby to cause operation of the trip.

2. In combination, a signal capable of limited rotation and a trip for operating the signal rigidly connected therewith whereby said signal limits the operation of said trip, said trip being mounted for oscillation in a vertical plane and embodying a pair of arms adapted for alternate engagement by a train-carried member, each of said arms being formed in two sections, one of which is carried by the body of the trip and the other of which is pivotally connected with the first named section, the last named section having engagement with the first named section permitting yielding thereof during engagement by the train-carried member to permit passage of the train-carried member thereover without operation of the trip in one direction and rigidifying the same to the first named section upon engagement thereof by a train-carried trip operating in the opposite direction.

3. In combination, a signal capable of limited rotation and a trip for operating the signal rigidly connected therewith whereby said signal limits the operation of said trip, said trip being mounted for oscillation in a vertical plane and embodying a pair of arms adapted for alternate engagement by a train-carried member, each of said arms being formed in two sections, one of which is carried by the body of the trip and the other of which is pivotally connected with the first named section, the last named section having engagement with the first named section permitting yielding thereof during engagement by the train-carried member to permit passage of the train-carried member thereover without operation of the trip in one direction and rigidifying the same to the first named section upon engagement thereof by a train-carried trip operating in the opposite direction, said last named section during engagement by the train-open ated member in the first named direction telescoping upon the first named section.

4. In signal operating mechanism, an oscillating trip adapted to be arranged adjacent the right-of-way and having angularly disposed anns arranged in the plane of oscillation and adapted for engagement by a member carried by a vehicle operating upon the right-of-way, said trip having pivotally mounted upon opposite sides thereof telescopic extensions for said arms. each having side walls embracing the sides of the arms and outer and end walls engaging opposite sides of the arm to limit movement of the extension upon the arm, and a spring attending between the arm and one of said walls to thereby normally maintain the other of the walls in engagement with the arm and to render the extension rigid to the arm when engaged from one direction.

In testimony whereof I hereunto affix my signature.

LEW'IS A. YOUNG.
